Answer:
3rd option. The way you do it is just plug in negative x value let's say -8, plug it in then y would be a positive value. So that rules out first two options. Then plug in positive x value, y would be negative.
I hope this helps you
x-3x= -4
-2x= -4
x=2
y= -3.2
y= -6
Answer:
Dora has to paint a total ol 60m
Step-by-step explanation:
4x5x3
4x5= 20
20x3=60
let the number be xy then
x + y = 12
y - x = 2 ( because y > x)
adding we get 2y = 14 so y = 7
and x = 12 - 7 = 5
So the number is 57.
87.2 - 25.9 = 87.2 - 26 = 61.2 + 0.1 = 61.3
